APPLICATIONS OF GEORADAR SCENARIATION TECHNOLOGY – PROJECTS

Detection of underground infrastructure objects

  • Detection and localization of the existing groundwater line
  • Analysis of the future (projected) route of groundwater
  • Analysis and location of all existing underground lines (objects) on the defined surface
  • Detection and identification of cluttered objects (manholes, wells, archaeological artifacts, underground passages, cellars …)
  • Pipeline leak detection (water damage)

Analysis of structural changes (objects / land)

  • Analysis of the state of the inner structure of the defensive embankments
  • Analysis of the state of the interior structure of the landslide
  • Analysis of the state of the internal structure of the concrete cover of the tunnel and surrounding land
  • Analysis of the state of the internal structure of concrete structures (poles, bridges, pavements …)
  • Analysis of the impact of irrigation / agrochemicals on the development of the root system volume
  • Analysis of the state of the garbage dump structure

Analysis of soil characteristics

  • Determination of the thickness of lithological layers of soil (land consolidation)
  • Determination of the type of soil in the lithological layer (land consolidation)
  • Groundwater level detection (up to 6m depth)
  • Determination of sediment thickness in rivers, canals and lakes
  • Determination of volume moisture content in the soil (hydrological characteristics)
  • Determination of spatial distribution of water / agrochemicals in soil
  • Geological research (wall and soil structure)
